Installation Recommendations
- Use Correct Tools: Use appropriate trim tools to avoid damaging door panels and clips.
- Check Connector And Pins: Inspect the 5-pin connector and wiring for corrosion or bent pins; clean terminals if required.
- Lubricate Moving Parts: Lightly lubricate latch linkages and pivot points with a suitable automotive grease to reduce wear and noise.
- Secure Fastening Torque: Tighten mounting screws to the vehicle manufacturer’s recommended torque where available.
- Final Check: Cycle the lock several times and check for smooth operation and correct locking/unlocking from remote and interior switch.
Reasons For Failure
